Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold structure for a new energy battery structural component. Background Technology

[0002] Injection molding is a core process in the plastics processing industry, and its molding quality and production efficiency largely depend on the rationality of the mold structure. When dealing with products that require extremely high surface finish and flatness, the conventional mold structure often fails to meet production needs.

[0003] To overcome the technical limitations of conventional molds, inverted mold structures have been gradually introduced. This structure places the ejection and injection systems on the male mold side, optimizing the ejection and cooling layout to some extent. However, existing inverted mold technology still has shortcomings in injection methods and ejection mechanisms. The injection path runs from the female mold side to the back of the male mold side and then into the cavity, resulting in a long runner, long molding cycle, and unavoidable sprue formation. Especially when used with advanced systems such as hot runners, it fails to effectively coordinate the relationship between ejection power transmission, hot runner operation stability, and overall structural simplicity. In summary, traditional inverted mold structures suffer from insufficient ejection force, low product flatness, long injection runners, and limitations in injection point selection.

[0004] Therefore, there is an urgent need for a new type of inverted injection mold solution that is highly integrated and has a reasonable structure. When dealing with products that have extremely high requirements for surface finish and flatness, the solution should systematically address key issues such as ejection stability, low product flatness, long injection channels, and limited selection of injection points, so as to improve the overall performance and production efficiency of the mold. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a new energy battery structural component injection molding reverse mold structure.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] Example 1: As Figures 1-6 As shown, this embodiment provides a new energy battery structural component injection molding backflow mold structure. The new energy battery structural component injection molding backflow mold is set on an injection molding machine and includes a male mold assembly 1, a female mold assembly 2, a mold frame assembly 3, and a hot runner injection assembly 4.

[0035] The mold frame 3 includes a base 31, a support plate 32 mounted on the base 31, an mounting plate 33 mounted on the support plate 32, and two side plates 34 mounted on the mounting plate 33. Linear drive components 35 are mounted on both sides of the mounting plate 33, and a movable plate 36 is mounted at the output end of the linear drive component 35. The movable plate 36 is located inside the two side plates 34. A guide rod 37 is mounted on the base 31, and a positioning hole 110 is provided on the male mold 11. Through the cooperation of the guide rod 37 and the positioning hole 110, the precise positioning of the male mold and the female mold is realized, effectively preventing mold misalignment and improving the consistency of product dimensions. It is especially suitable for the production of multi-cavity or complex battery components.

[0036] The female mold assembly 2 is equipped with an ejector assembly 5.

[0037] The hot runner glue injection assembly 4 includes a hot runner plate 41, a hot nozzle 42, and a valve needle that controls the opening and closing of the corresponding hot nozzle 42.

[0038] The female mold assembly 2 includes: a female mold plate 21, which is mounted on the side plate 34; and a female mold core 22, which is mounted inside the female mold plate 21.

[0039] The male mold assembly 1 includes: a male mold plate 11, which is disposed on the female mold plate 21; a male mold core 12, which is installed inside the male mold plate 11; and a top plate 13, which is installed on the male mold core 12. The ejection assembly 5 includes an ejector pin 51, which is installed on the movable plate 36.

[0040] Working principle:

[0041] In the actual injection molding process, the injection molding process of this new energy battery structural component is as follows: First, the hot runner injection assembly 4 starts to operate, and the molten plastic material is transported to the hot nozzle 42 through the hot runner plate 41. The opening and closing of the hot nozzle 42 is precisely controlled by the valve needle, so that the plastic material is injected into the mold cavity between the female mold core 22 and the male mold core 12 according to the preset path and flow rate.

[0042] At this time, the male mold assembly 1 and the female mold assembly 2 are in the closed state, the male mold plate 11 and the female mold plate 21 are tightly fitted, and the male mold core 12 and the female mold core 22 together form a complete cavity shape, providing molding space for the plastic raw material.

[0043] After the plastic raw material is filled into the cavity and cooled under pressure for a certain period of time, the mold enters the mold opening stage.

[0044] The injection molding machine pushes the male mold assembly 1 and the female mold assembly 2 apart, and the male mold plate 11 and the female mold plate 21 separate. The linear drive component 35 drives the movable plate 36 to move. Since the ejector pin 51 of the ejector assembly 5 is mounted on the movable plate 36, the ejector pin 51 will move synchronously with the movement of the movable plate 36, smoothly ejecting the molded new energy battery structural component from the female mold core 22. The guide rod 37 corresponds to the position of the positioning hole 110.

[0045] In this process, the cooperation between the guide rod 37 and the positioning hole 110 plays a key role. The guide rod 37 provides precise guidance for the movement of the male mold plate 11, while the positioning hole 110 ensures that the male mold assembly 1 and the female mold assembly 2 can be accurately aligned each time the mold is closed, effectively preventing mold misalignment and thus ensuring the consistency and stability of product dimensions.

[0046] In summary, this utility model effectively simplifies the overall mold structure by integrating the hot runner injection component 4 and the ejection component 5 on the female mold side of the mold base 3, avoiding the matching errors and vibration problems caused by the dispersed arrangement of the system in traditional injection molds, and improving the operational stability of the mold during high-speed injection molding.

[0047] By setting a linear drive component 35 to directly drive the movable plate 36 to drive the ejector pin 51 to achieve the ejection action, the ejection force transmission path is short and the response is rapid, which can meet the high requirements for the surface smoothness and flatness of the product and improve the stability and reliability of the ejection process.

[0048] The hot runner plate 41 and hot nozzle 42 are arranged on the fixed side of the mold and work with the valve needle to control the opening and closing of the gate, which effectively reduces the melt flow resistance and heat loss, improves the uniformity of injection filling and appearance quality, and is especially suitable for new energy battery structural parts with high surface quality requirements.

[0049] This mold has a compact structure and coordinated movements, making it easy to integrate with automated equipment such as robotic arms and conveyor belts. It enables rapid mold changes and continuous production, significantly improving production efficiency and product qualification rate, and has good prospects for industrial application.

[0050] In summary, this utility model has the advantages of reasonable structure, stable ejection, high integration of hot runner, accurate positioning and adaptability to automation, and is particularly suitable for injection molding scenarios with high-quality requirements such as structural parts for new energy batteries.

[0051] Example 2: Figure 7 As shown, in this embodiment, the movable plate 36 has circular grooves 361 on both the upper and lower surfaces. A T-shaped sleeve a351 is installed at the output end of the linear drive 35. A T-shaped sleeve b352 is installed on the T-shaped sleeve a351. An elastic connector 353 is fitted on the outer side of the T-shaped sleeve a351 and the T-shaped sleeve b352. The elastic connector 353 abuts against the circular groove 361. A circular hole 362 is opened in the movable plate 36. The T-shaped sleeve a351 and the T-shaped sleeve b352 pass through the circular hole 362. There is a gap between the T-shaped sleeve a351 and the T-shaped sleeve b352 and the circular hole 362.

[0052] The linear drive component 35 is preferably a hydraulic cylinder. During use, the output shaft of the linear drive component 35 may become misaligned due to wear. At this time, the elastic connector 353 acts as a buffer and can tilt and deform. When the T-shaped sleeve a351 and T-shaped sleeve b352 deflect, they can still push the movable plate 36 to move normally, ensuring the stable operation of the device.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
